Abstract (en)
[origin: EP3736509A1] A refrigeration system includes at least one refrigeration circuit 2. The refrigeration circuit 2 comprises a compressor 10, a first heat rejecting heat exchanger 6, a second heat rejecting heat exchanger 8, an expansion valve 12 and a heat absorbing heat exchanger 4. The refrigeration circuit 2 further includes a heat recovery control valve 14 for controlling flow of the compressed refrigerant fluid between the first heat rejecting heat exchanger and the second heat rejecting heat exchanger. The first heat rejecting heat exchanger 6 is for receiving compressed refrigerant fluid from the compressor 10 and exchanging heat between the compressed refrigerant fluid and a second fluid to increase the temperature of the second fluid, for example for heat recovery by heating water. The second heat rejecting heat exchanger 8 is for receiving the compressed refrigerant fluid and exchanging heat with ambient air to cool the compressed refrigerant fluid. The heat absorbing heat exchanger 4 is for heat exchange between the expanded refrigerant fluid and a third fluid to decrease the temperature of the third fluid. The heat recovery control valve 14 has a variable opening and the refrigeration system 2 is arranged to control the size of the variable opening based on at least one of the temperature of the ambient air and the temperature of the second fluid after heat exchange with the refrigerant fluid.
